Image Display and link displays
Although HL7 V2.4 supports the transmission of images and links in OBX segments, receiving systems are generally not capable of processing them and hence the retention of the fax machine.
The following implementation notes will improve inteoperability:
| Image format type | Recommended support | Notes |
|---|---|---|
| JPEG (lossless) | Support encouraged | |
| PNG (lossless) | Support encouraged | |
| TIFF (lossless) | Support optional | Optional support is due to requirement of multi-page support. Multi-page TIFF images should only be transmitted following site specific negotiations. |
Notes:
- The ED datatype supports images in OBX segments.
- Web hyperlinks should optionally be implemented using the RP datatype.
- Receivers must be able to access web references and the ongoing availability of of the data should be considered.
- For pathology data retention refer to the NPAAC guidelines.
